Aurora Granite Image

Description: Aurora granite is a medium to coarse-grained, grey-pink-black migmatite of the Precambrian period. This stone internationally may be nominated as a granite but in the area of application of the European Standard this stone must be nominated as a migmatite. During the polishing process a clear epoxy resin filler may be used to fill any micro fissures or tiny pitting however this does not affect the integrity of the stone, it merely provides an even smoother surface finish. Aurora Granite is suitable for both interior and exterior use futhermore is frost resistant and with a constant polish.

Products: Suitable for construction projects both commercial and domestic, prefabricated countertops/worktops, vanities, tiles, backsplashes, paving, fireplaces and memorials.

Surface Finish: Aurora Granite looks best with a gloss polished surface but is also available as honed, leather/satin, river-washed/antique, thermal/flamed, brushed and sandblast finish.

Sealing: Test with a small sample. It is possible that a sealant can be used on Aurora however excessive attempts at sealing it could actually create a residue film build-up.

Block Sizes: This is a quarry yielding selectable, grades of granite with blocks suitable for gangsaw size down to economical tile-sized blocks. For commercial projects it is important to ensure that blocks are selected from the same quarry face.

Rough blocks are usually exported by Break Bulk however intermodal containerisation is available at extra cost. Finished products are packed into sea-worthy wooden crates and loaded into containers.

Quarry Location: Aurora granite is quarried near Maentsaelae, Finland. Quarried since 1988 there are several quarries of this granite.

Synonyms:

Migmatite: A rock at the frontier between igneous and metamorphic rocks. They can also be known as diatexite. In many cases the darker part of the rock, consisting of biotite mica and hornblende, has been intruded by veins of lighter rock consisting of quartz and feldspar. A rock composed of a metamorphic (altered) host material that is streaked or veined with granite rock; the name means "mixed rock". Such rocks are usually gneissic (banded) and felsic rather than mafic in composition.

Mineral Composition: Average Plagioclase 60%, Quartz: 24%, Amphibole: 9%, Biotite: 7%
